Bill, I think the power company is taking care of the payback aspect. Looking at my daily log for the past few years, we're about three weeks ahead of the normal heat curve. I try to get as much yard work accomplished in the early morning as I can and then find something cooler to do in the afternoons. Today I went shopping and came home with a nice rain barrel. I'll show pics on my lanai project thread when I get it set up.
Jim
